There are some miscellaneous Hearthstone props scattered around. Frostmourne is clearly visible, but if you look closely, the hat I wore from the Witchwood cinematic is on display just over my shoulder

The book prop was phenomenal, it has relevance for something we’re revealing later. Inside, the prop is actually the “I” volume of an old encyclopedia. I would read aloud from it between takes

I didn’t get to keep the murloc slippers, sadly. They make little gurgle sounds with each step!

Believe it or not, it came in really handy as a game developer. I did a lot of directing as well, and when you direct a play, you're trying to create something with a group of creative people, trying to arrange everyone around a shared vision. The end product is different, but the process is really similar when you're making a game together.
